The new Philip Harris GM Probe has been developed by our own in-house experts who sought to provide a more versatile and cost effective option for the general usage of a Geiger Muller tube in schools and colleges.

• Detects alpha beta and gamma radiation.

The probe has a BNC connector and it does not require a separate holder meaning it can easily be mounted positioned and held using a retort stand and clamp.

The probe is compatible with timers and counters that require an external anode resistor (including the Philip Harris S-Range Digicounter).

Please Note: this GM Probe is not suitable as a replacement for the ZP1481 Tube used for the undertaking of the annual Radioactive Source Testing in schools. It is for classroom use only.
